If you look at it from the point of view of fitness and health preservation, of course it is better to drink light tea. The "Tea Drinking Tips" widely circulated in the Chinese folks said: "Light tea and warm drinking are the most nourishing", "Drinking tea is the most addictive to tea", which emphasizes this truth.

Why is it not recommended to drink strong tea?

1▪Strong tea hurts the stomach

The content of theophylline in strong tea is relatively high, which can stimulate the parietal cells of the stomach and cause hyperacidity. Drinking strong tea for a long time can easily cause excessive gastric acid secretion, which can cause serious problems for patients suffering from gastric ulcer and duodenal ulcer. Adverse consequences.

According to statistics, 10% of tea addicts will experience nervousness, anxiety and shortness of breath when drinking 2-3 cups of strong tea a day. The caffeine in tea has the disadvantage of being addictive. It can encourage people to drink more and more, which will harm people's health.

The content of theophylline in weak tea is less than that in strong tea, which is enough to refresh one's mind and restore physical strength, but it will not make people over-excited.

2▪Strong tea hinders nutrient absorption

Strong tea also contains a lot of tannic acid, which will hinder the body's absorption of iron, which is manifested as iron deficiency anemia. It can also be combined with protein and vitamin B1 in food, leading to constipation. Nutrition experts have found that excessive tea drinking will increase urine output and cause the loss of important nutrients such as magnesium and potassium.

3▪Strong tea ruins sleep

Tea contains 2% to 5% caffeine, and the caffeine content in strong tea is even higher. A cup of strong tea contains about 100 mg of caffeine, so drinking tea, especially strong tea, will make people excited and sleep less.

Then why do some people have no obvious sleep loss after drinking tea? Because everyone has different tolerance and metabolic capacity for caffeine. For people with strong caffeine tolerance, the excitement effect of caffeine is low, and it is easy to fall asleep naturally.

4▪Strong tea hurts blood vessels

Excessive caffeine will not only affect sleep, but also cause brain excitement, restlessness, insomnia, heart palpitations and other discomforts, which will increase blood pressure.

Drinking strong tea will increase blood volume, and to a certain extent, it will also increase the burden on the heart and the symptoms of heart failure. These are sometimes very fatal to patients with cardiovascular and cerebrovascular diseases.
